Embodiment 1

[0183] (Preparation of molds for anti-glare film production)

[0184] An aluminum roll (A5056 based on JIS) having a diameter of 200 mm was prepared on the surface of which copper ballard plating was performed. The copper ballard plating consists of copper plating / thin silver plating / surface copper plating, and the overall thickness of the plating is set to about 200 μm. The copper-plated surface is mirror-polished, and a photosensitive resin is applied to the polished copper-plated surface, followed by drying to form a photosensitive resin film. Next, use the laser to align the Figure 15 A pattern composed of image data shown in , is exposed on a photosensitive resin film and developed. Exposure and development by laser were performed using "Laser Stream FX" (manufactured by Think Laboratory Co., Ltd.). A positive photosensitive resin is used for the photosensitive resin film. Figure 15 The pattern shown in is a pattern in which a plurality of dots with a diameter of 12...

Embodiment 2

[0191] In the exposure process of mold making, laser exposure is performed on the photosensitive resin film to Figure 16 The pattern formed by the image data shown in is a pattern formed by repeating and juxtaposing a plurality of patterns in succession. The etching amount in the first etching process is set to 5 μm, and the etching amount in the second etching process is set to 12 μm. , Mold B was produced in the same manner as in Example 1. Except having used the mold B obtained, it carried out similarly to Example 1, and produced the antiglare film B. Figure 16 The pattern shown in is a pattern obtained by randomly arranging a plurality of dots with a dot diameter of 12 μm and applying a spatial frequency of 0.035 μm -1 The following low spatial frequency components and 0.135μm -1 The above-mentioned high-spatial-frequency components are removed by a band-pass filter.

Abstract

The invention provides an anti-dazzle film and an anti-dazzle polarizing plate using the same, the anti-dazzle film comprising a base material film and an anti-dazzle layer with a concave-convex surface arranged on the base material film, wherein the base material film contains an acrylate serial resin; the ratio H12 / H22 of the energy spectrum H12 of elevation of the concave-convex surface at the spatial frequency of 0.01-1 micron to the energy spectrum H22 of elevation of the concave-convex surface at the spatial frequency of 0.04-1 micron is 3-20; the ratio H32 / H22 of the energy spectrum H32 at the spatial frequency of 0.1-1 micron to the energy spectrum H22 is at most 0.1; the concave-convex surface comprises 95% of surfaces having an angle of inclination of at most 5 degrees.

Description

technical field [0001] The present invention relates to an antiglare film and an antiglare polarizing plate using the same. Background technique [0002] For image display devices such as liquid crystal displays, plasma display panels, Braun tube (cathode ray tube: CRT) displays, and organic electroluminescent (EL) displays, when external light shines on the display surface, visibility is significantly impaired. In the past, in order to prevent the reflection of such external light, in TVs, personal computers that value image quality, video cameras and digital cameras used outdoors where the external light is strong, and mobile phones that use reflected light to display, image display The surface of the device is equipped with an anti-glare film to prevent external light from being reflected. [0003] For example, in Japanese Patent Application Laid-Open No. 2006-053371, it is described that after performing sandblasting on a ground mold base material, electroless nickel pl...
